The large intestine starts as a pouch called cecum and continues as the ascending, transverse, descending and sigmoid colon, followed by the rectum and anus. The large intestine has the same four layers as other parts of the digestive tract. It is lined by simple columnar epithelium The large intestine is subdivided into four main regions: the cecum, the colon, the rectum, and the anus. The ileocecal valve, located at the opening between the ileum and the large intestine, controls the flow of chyme from the small intestine to the large intestine Gross and Microscopic Anatomy of the Large Intestine. The large intestine is that part of the digestive tube between the terminal ileum and anus. Depending on the species, ingesta from the small intestine enters the large intestine through either the ileocecal or ileocolic valve. Within the large intestine, three major segments are recognized The large intestine mucosa is relatively smooth and there are no plicae circulares or intestinal villi present. muscularis externa - gastrointestinal tract outer smooth muscle layer formed generally by an inner circular and an outer longitudinal layer, in the colon the outer layer form the taenia coli
The large intestine feeds into the rectum, which stores the feces and has a columnar epithelium with abundant goblet cells. Feces pass out of the rectum, through the anus, and out of the body. The anus is characterized by a stratified squamous epithelium that undergoes a gradual transition to skin containing sebaceous and apocrine sweat glands Histology Digestive Page 1 Frame.

The large intestine, also known as the colon, is part of the digestive tract. The digestive tract includes the mouth, esophagus, stomach, small intestine, large intestine, and rectum. The large intestine is approximately 5 feet long, making up one-fifth of the length of the gastrointestinal (GI) tract. The large intestine is responsible for processing indigestible food material (chyme) after. Small intestine. The small intestine is a long tube that extends from the stomach to the junction with the large intestine (a.k.a colon.) The major functions of the small intestine are digestion, secretion, and absorption. The small intestine is divided into three segments: duodenum, jejunum ; ileum Histology of the mucosa, submucosa and muscularis. The histological section shows three of the four layers of the colon - mucosa on the luminal side, submucosa of loose connective tissue and the muscularis. Note how the mucosa is thrown into folds of tightly packed crypts resembling a line of test tubes Cecum, ascending (right sided) colon, transverse colon, descending (left sided) colon, sigmoid colon, rectum. Cecum: In peritoneum, 6 x 9 cm. Large blind pouch arising from proximal right colon. Blind end directed downward, open end directed upward. Ascending colon: 15 - 20 cm long. Posterior surface is in retroperitoneum, but anterior and. 1.5 - 2 m in length and 100 nm in diameter. PAS positive, actin myosin complexes. Goblet cells: Occur in crypts and surface absorptive cells. Decrease towards villus tip, increase in frequency along small intestine (most numerous in lower ileum) Columnar in shape, mucus droplet in supranuclear area, secretes mucus, ions and water
The mucosa of the large intestine is characterized by the presence of crypts of Lieberkühn, associated predominantly with goblet cells intermixed with a few absorptive and enteroendocrine cells. Glucagon-like immunoreactant (GLI), pancreatic polypeptide-like peptide (PYY) with N -terminal tyrosine amide-producing L cells predominate in the. . The large intestinal wall is made up of four layers. Mucosa is the innermost layer of the large intestine surrounding the lumen; Unlike small intestine, the mucosa here is free of villi and has a soft surface; It is made up of single-layered columnar epithelial cells Figure 23.22 Histology of the large Intestine (a) The histologies of the large intestine and small intestine (not shown) are adapted for the digestive functions of each organ.

Outer Appearance of the Large Intestine. The large intestine is approximately 1.5 m long and measures about 5-8 cm in diameter. It runs around segments of the small intestine like a framework.

The colon (large intestine) is the distal part of the gastrointestinal tract, extending from the cecum to the anal canal.

The digestive system consists of the digestive tract, or gastro-intestinal (GI; gas′tr ō-in-tes′tin-ă l) tract, plus specific associatedorgans. Because the digestive tract is open at the mouth and anus, the inside of the tract is continuous with the outside environment, and food entering the digestive tract may contain not only useful. As seen in the diagram to the right, the intestines are, in essence, suspended from the dorsal aspect of the peritoneal cavity by a fused, double layer of parietal peritoneum called mesentery. In come cases, parietal and visceral peritoneum are also continuous along the ventral abdomen, where they are called ventral mesentery The mucosa of the large intestine is smooth; there are no villi or microvilli.The mucosal glands are much longer and straighter. The number of goblet cells in the mucosa is increased compared to the small intestine, as mucus is very important for lubrication of the ingesta as it passes through the intestine, particularly as more water is absorbed from the lumen making chyme drier Ion Absorption in the Loop of Henle.

The large intestine, or colon, is the section that continues from the small intestine to the anus of the animal. Any undigested food and all the fiber from the rabbit's diet will pass from the small intestine to the large intestine. At this point, the rabbit's digestive system is able to sort the material into two portions - that which.

The small and large intestine together form one of the largest organs in the rat. The intestinal tract is divided functionally into the small intestine (duodenum, jejunum, and ileum) and the large intestine (cecum, colon, and rectum). This can be remedied at the time of necropsy or tissue trimming if labeled segments.
Villi, or tiny projections, line the wall of the small intestine. The duodenum is the first section of the small intestine. The histology of the duodenum is characterized by microscopic structures called Brunner's glands. The serosa generally performs the outer part of the duodenum.

The small intestine is about 6 meters (m) long and consists of three parts: the duodenum, the jejunum, and the ileum (figure 16.13).The duodenum (doo-od′̆e-n̆um, doo-̄o-d̆e′n̆um) is about 25 cm long(the term duodenum means 12, suggesting that it is 12 in. long).The jejunum (j̆e -joo′ n̆u m) is about 2.5 m long and makes up two-fifths of the total. The small intestine is an organ located within the gastrointestinal tract.It is approximately 6.5m in the average person and assists in the digestion and absorption of ingested food. It extends from the pylorus of the stomach to the ileocaecal junction, where it meets the large intestine at the ileocaecal valve.Anatomically, the small bowel can be divided into three parts: the duodenum.

Anatomy. The duodenum has been described as a C-shaped or horseshoe-shaped segment of the small intestine. It is located below the stomach. This portion of the small intestine received its name due to its size; in Latin, duodenum translates to 12 fingers, which is the approximate length of the organ. 1 The duodenum can be separated into. Beneath the Muscularis Externa lies the Serosa, a thin layer of connective tissue and mesothelial cells that line the outer surface of the large intestine. Histology Colon.

Domesticated carnivores (dogs and cats) have a single-compartment (simple) stomach that is entirely lined by glandular mucosa. The stomach is divided into several segments. From oral to aboral they are: cardia, fundus and pylorus. The glandular stomach is so named due to the high secretory function of the mucosal epithelium. The small intestine is the part of the GI tract that lies between the stomach and the large intestine. The small intestine is where most of the digestion and absorption of food takes place.
